OCEANIC MANTA RAY
There have been fewer than 10 recorded sightings of Manta birostris on the eastern side of Australia. Little is known about them. This one was quite small with an approximately 3.5m wingspan. These ocean giants have been recorded up to 7m wide, though not all adults reach this size.
